lpplioation filed October 26. 1907. Serial No. 399,282.

To all whom it may concern:

Be it known that I, lsIuoR Coornn, a. citizen of Switzerland, residingat the horough of Brooklyn, city of New York, county of Kings. and Stateof New York. have invented :ertain new and useful improvements inAutomohile- Radiators, of which the following, is aspecification,reference being had therein to the accompanying drawings,which form a part thereof.

My invention relates to automobile radia tors, and more particularly tothe manner of constructing and assembling same to cure the requiredefficiency and facilitate cleaning and repairs.

The main object of the invention is to provide an automobile radiatorwherein the circulating water cooling system is independent of theradiator frame, and said frame is so divided or split as to constitute asectional frame which may be readily taken apart to facilitate theassembling of the radiator or the removal of the-coining system forpurposes of cleaning and repairs.

A further object is to provide an automobile radiator which will havethe appearance and finish of the ordinary unitary rad iator, While beingcapable of being quickly taken apart to permit the repairing ot' theframe, or the cleaning or straightening of clogged or injured tubes.

A still further object is to provide an automoliilc radiator wherein theframe acts solely as a keeper or housing for the circulating; watertubing, and forms no part of the channel for the circulating Water. thuspermitting said parts to be manufactured and repaired entirelyindependently of each other.

A still further object is to provide an automobile radiator, wherein allof the circulating water tubes will be straight, and open outwardly intoa closed chamber having a water tight hut removable closure, andpartitions. forming a tortuous channel throu h all the radiator tubes,thus giving the resircd circulation through air cooled tubes whilepermitting such convenient access to the tuhes as to facilitate repairs.

A still further object is to provide an autoniobile radiator wherein theframe will be made of two separable channeled parts, the bottom of whichwill he secured to the under frame or bolster of an automobile, and theupper one, or cap, may be removed therefrom and from the machine topermit the radiator tubes to he quickly removed from an autonmhile,without injury to, or work upon the frame itself. And a still furtherobject is to provide an automohllc radiator which may he inexpensivelyproitluced and which will lie so assembled as to make to pairs theretopossible with little labor and small expense.

The invention consists primarily in an automobile radiator comprising acirculate inp; Water system independent of the radiator frame, asectional radiator franuadapted to receive and retain said stem, andmeans uniting the sections of s. lll frame whereby said frame may betaken apart and the water cooling system l'llllHYHl tlurcfrom: and insuch other novel features of construction and combination of parts asare likl'tllh after set forth and (lo-scribed. and more particularlypointed out in tin. claims hereto tilit'itlltltl.

Referring to the drawings: Figure l is a perspective view of the fronthood of an untomohile. showing my radiator in position hereon; Vie. L isa front view of said radiator partly in section and pa rtly ini-ltvatiou: and Fig. 3 is a. section on the line fi t; of Fig. 2.

TrlkL. letters refer to like parts throughout iho several views.

in repair work on automobiles. l' have found that where injury to anautomobile results from a collision. the radiator. lining: at llioextreme front of lllt' nmchlne. is mo t llfllllt to injury. the framefrequently lllillf bent and the tuhes bent or denied. In ad llition tothis. the sedinant in the cooling: water in deposited in S ll-ll quantites in the i'iri'u atinp' water cooliiur system. as to oi ulruci' thetuliez 'parliallv or wholly. thus impairing or dc-troyinz5 the effiiency of the radiator. it is now a common. if not a sou cral practice inthe nianuhwturc of automo hile rz'wliators to form the air cooled tube:of a siuc le continuous s nuous l lllP or ipe. or a group or ne t of soh. and o older or brace the frame thereto. thus uiliziug the frame fordecorative or tiuishiiur purposes solely. and making it !1t*."0-?-:l! incase repairs to the tube are required. to remove the entire radiator F'r me and all. from the automohile. remove f e frame from th tubes hnumzikin" the oidered or lllll"t"(l ioin s rim} after repairs areeffected. resolder or rein-a the frame to the tubes. This prm'orlul'e inslow and costly and is required to etfeet any repairs whatever whethersuch amounts to the installation of new tubing or the removal of anunsightly dent in the frame or the tubes, which docs not affect theetliciency of the cooling system. This fixed heavy cost often causesautoniobilists to defer making repairs not materially ntfecting theefficiency of the radiator, and leads to many troubles through theclogging of the cooling system. In my rescnt invention, I aim to avoidthis item of expense by making the structure of the radiator such thatany part may be readily and cheaply accessible, thus permitting the topof the frame to be removed for repairs without disturbing the tubing, orthe tubing itself, to be .so quickly removed and replaced as toeliminate those expensive operations above referred to. Incidentally, Iaim to so construct and arrange the cooling tube system that after ithas been removed, it may be quickly repaired, and Without impairing itscilicicncy. In the accompanying drawings I have shown an embodiment ofmy invention by which I accomplish such results.

'In the drawings, I have shown at a the bolster or under frame of anautomobile. Mounted on said bolster or under frame a, is the radiatorframe, which consists of a bottom part I) and a top frame 0 of theradiator frame. Each of these sections 7/ c is provided with back andfront flanges 6' 5 i '7 extending entirely around same. the

flange 5 being adapted to be caused to aline with the tango c and theflange. b with the flange r These flanges form a continuous channeladapted to rcrcive the tube system. and are of a width which isvariable, so as to inelosc the ends, op and. bottom of said sys tem, anddisclose forwardly thereof only a series of straight tube sections, andsufficient thereof to expose as great an arm of tube surface to the aircurrents as is feasible without sacrificing thc decorative appearance ofthe radiator. The bottom section b is provided with a laterallyprojected lug d on each side thereof adapted to rest upon and be secured.to the frame a by means of the screw threaded stud c passing through anopening therein and projetting upwardly, thus-causing said part to besuspended from said frame. The top frame 0 is provided with similar lugsat adapted to pass over the upwardly projected ends of the screwthreaded stud P and be lamped upon tho lugs 11 by means of the nuts c ina manner to make said franu', when assembled practiculiy a continuousframe, both. in function and in appearance. To can-so tho clumpingaction ot the nuts is or the flanges d to firmly bind the radiator tubesystem Within the housing formed by tho lii part frame Ei--c, 1 providesaid parts respectively with a plurality of nubs f f f pro ecting intothe channel within said frame at divergent themselves are each points,thus avoiding the necessi for having the contacting parts of the Taniaand the radiator tube system erfectly true, while holding the radiatortn e system ti ht, I have shown these nubs as bein ma e integral withthe frame, and of the same material, but their construction and arrangement is immaterial as long as they pro ide reasonably stable widelydivergent contact points beurin upon the radiator tube' system on all sias so as to prevent a rattling of said system within said frame.rangement gives the desired stability to the radiator as an entiretywithout the necessity for soldering or brazin the frame and the tubesystem together. %he top frame a has centrally of .the top thereof, an oenin c adapted to receive the neck of t o filing nozzle of the tubesystem, and the bottom section b has an opening I) thercthrough adaptedto permit the drain cock to project below said frame. The flanges b care also provided with slotted openings 6 c to allow a clear field forthe leads coupled to the pipes to the circulating system for the ongins, in order to permit the removal uf the cap or crown r, and of thetube system itself.

While various typos of air cooled tubes' may be employed, in carryingout my invention, l preferably employ a special type of such especiallyadapted for use in connection with a iii-part frame, as described. Inthis type of tube system, I em loy a tube system proper, having so faras t e circulating system is concerned, the efficient:

of certain well known condensers, but di 't'cring therefrom in that thetubes are flattcucd, and of a width substantially equaling that of theentire radiator. These tubes extend from side to side in a straightline, and cach cud thcrcuf discharges into :1 casinn formed of an innershell. 9' and outer shell 72, which shells are united by water tightsides 11 to form a top, a bottom and two sido chambers. To make thetubes j accessible, for cleaning and repairing purposes, I form theshell I! on each side of the radiator, of a plurality of int'lepcndentplates l1 /1'- attached to the sides i by a. temporary joint as ofsolder thus permitting a single data It it to be ronuived Withoutdisturb mg the remaining plutcs. The top of the shell 9 is cxtcndcd onne side to close the side chamber on that side, and the bottom of the.shell g is similarly cxtcudcd to close the other side chamber. The sidechambers divided by partitions 7c 7". it into a plurality of independentchambers each having one or more tubes y discharginp, thoreinto and loadng thorn from, uch partitions being so staggered as to set up acontinuous circulation from the: top chamber through the various tubes jfrom one side t'llilllll'lQI' to the othcr. finally discharging intothe. bottom chamber. The

This arradiator casino has a lead in through which water from the engineis dischargwl into the top chamber lllcreol and a second lead w, throughwhich water is drawn by the pump from the bottom chamber, each said leadbeing coupled to the circulating pipes adjacent to the radiator so as tofacilitate the disconnection t'theradiator. (.onnrcted with the bottomchamber of the casing It is an ordinary drain cock 0.

The opcrai ion of the herein described radi' ator is substantially asfollows:----'lhe bottom frame 5, the top frame m and the radiator properit jareinadccomplete, and a part from each other. and the device isassembled by first placing the studs 1- in the vehicle fra 1ne (I withthe screw threaded end projecting upwardly. The bottom frame F) is thenmounted on said frame by sliding the lugs at over said studs thusforming a hanging channel supported directly from the frame (t asdescribed. The radiator proper is then deposited. in this Frame, thedrain. cook 0 passing through the opening I) therein, and the lead apassing" through the slot I) in the flange 0' until the radiator comestot-est upon the nnbs 7. The top frame, a, is then brought with the sideflanges c thereof in closing the edges of the casing 1t and the said topfrairin rn p or crown slid upon the Said casing until the lugs d thereonpass over the studs r thus bringing the flanges b 0 c a into dircstnlinezuent with each other, and with their adjoining edges into suchclose proximity as to make it possible by drawing the two sections ofthe frame together bymeans of the nuts 1:. to form a practicallyinvisible joint at this point. This clam ping of the two sections closeto ether also l'JIlI'tgS the nubs f firmly upon tie top of the casing 72so as to bind said casing bet ween said nubs and the bottom nubs Theside nabs f are also brought, by this operation. into such positionrelative to the sides 01 the casing it as to prevent a lateral movementof said casin \Vhen so assembled the filling), nozzle p asses throughthe openings c. the cap 0 said nozzle being removed if said opening isnot large enough for this purpose.

hen the device has been an as embled, the leads m n are coupled to theirrespective pipes of the circulating Water system to and from theengines. A

In operation, the vater from the water 'acket of the engine passes tothe top chamer of the casing h h passing therefrom to the topmostindependei'it chamber of one side ehamber,'ahove the partition through aplurality of tubes to the npperrnostinde pendent side chamber on theoppositeside thereof and back and forth from side chem-- be! to Sidechamber in the course defined by the partitions 1c is finally disehar;g1 El i-J the bottom chamber and being (litt't i there from through thelead a The tubes j being pnundcd out. or other repairs .l'lltll'lOthereto uickly; all parts thereof being readily aecessiblc. andrequirilng no cleaning to prepare them for such work. ll. however, thetubes themselves require cleaning. or repairing. the top frame 0 isrcnnn-ed as above, the pipe connections between the radiator and thecirculating water s \'.-tem are uncoupled,

and the radiator itself is lifted from the bottom frame. To get accessto any particular tube when the repairs are local. it is merelynecessary to remote one of the detachable side plates 2 or ll oppositethe end of the tube to be repaired, by unsoldering or undo ing any othermeans securing it in place, thus exposing the other end of the tube in amanner to permit the insertion of the tools necessary to remove anydents or force any obstructions therefrom. If desi ed, all of these sidelates may be removed quickly and quickly replaced to effect repairsthroughout the radiator. It will thus be seen that in case of damage tothe hanging bottom frame. this frame always remains upon the nlachine.and that the radiator may be dismembered quickly and as quielrlyreassembled, thi. i etlecting a material saving in the cost of repairs,and at the same time avoiding the necessity to uninake a soldered orbrazed joint betucen the frame and the tubes. and reunite these parts byresoldering or rebrazing. \Yheu so assembled the front flanges e Zextend over the sides 6 in a; manner to expo-e only the tubes 1' thusserving to give finish to the radiator, and at the same time serve asretaining flanges for the radiator casino," and tubes.

I am aware, that in surface condensers, a circulating system consistingof a plurality of staggered chambers connected by'a ph1- rality ofstraight pipes, so as to cause a at zag circulation from the top to thebottom 0 the condenser is old in said art, and I do not intend to claimsuch broadly. The requirements peculiar to the automobile industrhowever, are such as to impart particular a vent-a es to this type ofradiator when so modi ed as to make the ends of the tubes readilyaccessible, and I believe this feature of the cooling system to be new.I also be have it. to be new to provide a bi-part separable frame,housing in the circulating water cooling system in a manner to permitthe attachment of one or more parts independently of the others, and Iintend to claim such broad] Having described my invention, what I claimas new and desire to have protected by Letters Patent is 1.
